The media has long noted Lance Armstrong's preference for wiry, long-faced blondes, and a new study shows he might have a hard-wired reason for his sexual predilection: these women look like his mother. (Pictured, from left: Lance's mom, Linda, his ex-wife Kristin, and ex-girlfriend Sheryl Crow). According to a new study, "men were more likely to pair up with women whose bone structure was similar to their own mothers, with a similar effect holding for womens' choice of men," the Guardian reports. Psychologists call this "sexual imprinting" and the study leader, Tamas Bereczkei at the University of Pecs in Hungary, says that this imprinting isn't just due to familiarity alone. "If that were the case, women would be drawn to men whose faces were similar to their mothers as well as their fathers," the Guardian points out.Professor Bereczkei and his team measured the facial proportions of 52 families during the course of the study, and found " significant correlations between the young men and their fathers-in-law, especially on facial proportions belonging to the central area of face - nose and eyes," the BBC notes, while "Women also showed resemblance to their mothers-in-law in the facial characteristics of their lower face - lips and jaw." Somehow, hearing from a guy that you have a mouth just like his mother's doesn't exactly endear. Science is creepy!
